Harvesting entanglement from the Lorentz-violating quantum field vacuum in a dipolar Bose-Einstein condensate
Zehua Tian, Weiping Yao, Xiaobao Liu +3
We theoretically propose an experimentally viable scheme to explore the transfer of nonclassical correlations from a dipolar Bose-Einstein condensate (BEC) to a pair of impurities…

Dissipation suppression for an Unruh-DeWitt battery with a reflecting boundary
Xiaobao Liu, Zehua Tian, Jiliang Jing
In the framework of open quantum systems, we study the dynamics of an accelerated quantum battery (QB), modeled as an Unruh-DeWitt detector interacting with a real massless scalar…

Dissipative dynamics of an open quantum battery in the BTZ spacetime
Zehua Tian, Xiaobao Liu, Jieci Wang +1
We consider how charging performances of a quantum battery, modeled as a two-level system, are influenced by the presence of vacuum fluctuations of a quantum field satisfying the D…
